I am a Medical professional at 71. Since about 25 years I have been suffering from Irritable Bowel Syndrome and severe weight loss, Weakness, exercise intolerance etc. For about 6-8 months I feel too weak after passing urine at night. Tiredness, lethargy, sweating and restlessness last for few minutes during which I have to switch on the fan even at a cool weather. I get up 3-4 times at night for passing urine. Blood Sugar, Urine analysis report are normal with minimal Prostatic enlargement detected in USG. Please help. Dr. Sujit Chakrabarty
